Answer:
standard error of the mean (S.E) = 0.06
Step-by-step explanation:
Explanation:-
Given sample size 'n' = 500
Given variance of the Population = 900
The standard deviation of the Population = √900 = 30
The standard error of the mean is determined by
[tex]S.E = \frac{S.D}{\sqrt{n} } = \frac{30}{500} = 0.06[/tex]

Answer:
you can't simplify further
Step-by-step explanation:
Here a easy one tooooooooooooo
Answer: See explanation
Step-by-step explanation:
1.) There's an angle supplementary to m∠123°, that angle is y
y and m∠123° are supplementary since they're linear pairs
y + 123 = 180
Subtract both sides by 123
y = 57°
Now we know at least two angles of the triangle, x + y + m∠92° has to be 180° because they form a triangle.
x + y + m∠92° = 180°
x + 57 + 92 = 180
x + 149 = 180
Subtract both sides by 149
x = 31°
2.) We have to figure out the missing angle in the triangle, that missing angle is once again, y.
y + 100 + 25 = 180
y + 125 = 180
y = 55°
x and y are supplementary angles because they form a straight line
x + y = 180°
x + 55 = 180
Subtract both sides by 55
x = 125°

Carrie can swim 190 meters in 2 minutes. If you graph this with minutes on the X axis and meters on the
Y axis, what will be the slope of the line?
Answer:
the slope is 95
Step-by-step explanation:
to find the slope of the line divide the change in y by the change in x
if x is minutes and y is meters
190/2=95

The area of a rectangle with sides of 8m and 12 m is 96 sq.
True or false
Answer:
true
Step-by-step explanation:
Answer:
True
Step-by-step explanation:
The area of a rectangle is A=lw.
If l=8 and w=12, then 8(12) = 96
Your units will be 96 sq. m, so the answer is True

Answer:
wx=51
Step-by-step explanation:
8a-5=5a+16
3a=21
a=7
8(7)-5=wx
wx=51
Answer:
The length is 56
Step-by-step explanation:
First, since WX and ZY are the same length, set them equal to each other and solve for a:
8a-5 = 5a+16
8a = 5a + 21
3a = 21
a = 7
Now, you can plug in 7 for a in the original equation and get:
8a-5
8(7)-5
56-5
51
51 is your final answer!

What happens to the mean of the data set {10, 2, 8, 9, 5, 2, 6} if the number 12 is added to the data set? A. The mean increases by 2. B. The mean increases by 12. C. The mean increases by 0.75. D. The mean increases by 1.75.
Answer:
C. The mean increases by 0.75.
Step-by-step explanation:
The mean of a data set is given by the sum of all its values, divided by the number of values.
Data set {10, 2, 8, 9, 5, 2, 6}
7 values
Sum: 10 + 2 + 8 + 9 + 5 + 2 + 6 = 42
Mean: 42/7 = 6
Adding number 12 to the data set
Now we have 8 values
The sum is 42 + 12 = 54
The mean is 54/8 = 6.75
This means that the mean increases by 0.75.
Answer:
C. 7.5
Step-by-step explanation:
the mean increases by it

Answer:
You only got one right the right answers are "the graph is decreasing in intervals (1) and (4)" and "The graph shows a constant function in interval (3)"
Step-by-step explanation:
I took the test.
Hope this helpssss
Answer:
Only statements 1 and 5 are true.
Step-by-step explanation:
Statement 1: True
In intervals 1 and 4, the graph slopes down to the right. That shows a decreasing function.
Statement 2: False
Interval 2 goes up to the right. That is an increasing function, not a constant functions.
Statement 3: False
The graph increases in interval 2 but decreases in interval 4.
Statement 4: False
The graph has intervals of increase, decrease, and constant value.
Statement 5: True
Interval 3 is horizontal, so it is constant.
Answer:
Statements 1 and 5 are true. All others are false.
